Huzhou Dongyao Chain Industry Co., Ltd. is one of the leading manufacturers and suppliers of b series short pitch precision simplex roller chain in China. With abundant experience, we warmly welcome you to buy high quality b series short pitch precision simplex roller chain from our factory. Also, custom service is available.
Product Overview
The DYLinkar B Series Short Pitch Precision Single Row Roller Chain is an industrial transmission chain meticulously manufactured in accordance with the international standard ISO 606 (equivalent to DIN 8187 and GB/T 1243). Compared to the A Series, the parts of the B Series are larger in size under the same pitch, and its structural strength and impact resistance are more outstanding. The single-row structure is suitable for industrial transmission scenarios with medium and low loads. The product undergoes strict size accuracy control and pre-stretching treatment before leaving the factory, ensuring precise pitch and reliable meshing. The DYLinkar B Series single-row roller chain is widely used in agricultural machinery, packaging equipment, material conveying, wood processing, and general industrial transmission fields.

Application
- Field transmission of agricultural machinery - applicable to agricultural equipment such as planters, tillers, and threshers.
- Packaging equipment and light industrial machinery - for intermittent reciprocating drives used in sealing machines, packaging machines, labeling machines, etc.
- Material transportation and sorting system - Compatible with belt conveyors, roller lines, lifting sorting equipment and other logistics equipment.
- Wood processing and general machinery - covers the transmission and speed regulation of equipment such as band saws, planers, fans and pumps.
Compatibility
Comply strictly with international standards - The size specifications fully meet the requirements of the European B-series standard, and can be interchanged with other brands of chains worldwide that also meet the same standard.
Customized B Series standard sprocket system - Under the same pitch, the inner pitch width and the roller diameter of the B Series and A Series are different, and they cannot be interchanged.
Installation dimensions are the same as those of the double-row models – The installation dimensions are exactly the same as those of the B-series double-row chains. The sprockets are interchangeable, and existing equipment can be installed and used without any modifications.
The connecting pieces must be of single-row specification - double-row pieces cannot be used for the connection and maintenance of single-row chains.
Wide range of alternatives to mainstream brand products of the same specification – Can directly replace the B series single-roller chains of brands such as Tsubaki, DID, RK, Donghua, Guaimeng, etc.

FAQ
Q:What is the proper procedure for installing a new industrial roller chain?
A:Installing a new industrial roller chain involves safety first (power off), followed by inspecting sprockets & shafts, ensuring proper alignment, fitting the chain around sprockets, correctly joining the ends with a master link (using a chain puller for tension), setting the correct sag/tension (approx. 1/4" per foot of span), and finally, lubricating and testing for smooth operation, with a recheck after initial use.
Q: What are the most common causes of premature roller chain failure?
A:The most common causes of premature roller chain failure are improper lubrication, overloading, contamination, and misalignment, often working together to cause accelerated wear, elongation, and fatigue.
